Kendall and Kylie Jenner's red carpet ensembles at the 2014 MuchMusic Video Awards are this Monday's buzz-building moment from over the weekend, for sure. But as jaw-droppingly sexy as the 18-year-old's pelvic bone-baring gown was—the duo also looked pretty sizzling during the show.

In fact, the co-hosts had three costume changes during Sunday's fête in Toronto, Canada. After the carpet, the duo kicked things off with dazzling duds—Kendall in a metallic blazer with matching hotpants and Kylie in a sparkling LBD. Next up, were the wild patterns. The upcoming model showed off her statuesque physique in an animal print frock by Julien Macdonald while her newly raven-haired sister rocked a studded-mini dress.
